COLUMBIA, S.C. -- The National Weather Service says patchy black ice is still possible in some parts of rural South Carolina.
The road conditions have prompted some school districts to delay the start of classes Friday.
The weather service said warmer temperatures Thursday allowed much of the snow to melt. But that is leaving some roads wet and temperatures dropping below freezing created patchy sheets of ice on secondary roads.
Forecasters say the same conditions are possible in the inland areas along the coast.
Low temperatures Friday ranged from 14 degrees in Cheraw to 37 on Hilton Head Island and Moncks Corner.
Major utilities reported no problems with service interruptions Friday morning.
